I think what is even worse sometimes is the hypocrisy: they openly condemn these things and suggest they would never act out, blame the client etc - and then do it all the time. I had a therapist like that, it wasn't sexual, but I fought with him for a while, hoping that he would see his patterns and accept responsibility, but to no avail. The response I most often got was to go to more sessions and discuss my anger with him, how it relates to my history etc. I never had anger issues before and my reactions were very much to him, not to someone else even though I do tend to react to manipulation and gaslighting similarly when someone attempts it (and won't allow it long). It became pretty maddening and I definitely felt harmful effects that were not there in my mind before at all; luckily stopped seeing him before it could have escalated.

Anyhow, for me it's this grandiose hypocrisy is what I despise in many in the so-called "helping professions".
